Ethical
Issues in Clinical
Research
·
Ethical obligation to do research
·
Risk vs benefit consideration in searching for new treatments
·
Informed consent
·
Information given for informed consent
·
Other considerations: randomization, patients under the stress of
disease may not fully understand the study and therefore their consent is not
free, failure to stop the study when harmful/beneficial effects appear.
Case Scenario - 1
·
The commander of an army brigade asked the brigade physician to
undertake research on causes of very high sick leaves. The physician took blood
from all soldiers to look for their immune profiles. When some soldiers
protested that they were not asked for consent he told him he was following
military orders.
Case Scenario - 2
·
A physician was recruiting patients for a large multi-center study of
myocardial infarction. The informed consent sheet was 10 pages long because
there were many procedural details and adverse effects to disclose. Most of the subjects were bored reading
through or listening to the details and were ready to sign because they trusted
the physicians doing the study.
Case Scenario - 3
·
A new drug that had proved efficacy against leukemia in invitro,
animal and phase 2 trials was submitted for human trials. Its risk profile was
not well understood from earlier studies. It was to be tested against a
placebo. There was no known effective treatment for this disease.
Case Scenario - 4
·
A multi-center trial of a new medication was carried out at a local
hospital; the hospital was among the last to join the 5-year trial. Local
results showed that the drug was effective and patients were satisfied. Interim
analysis of the data by the sponsor showed the superiority of the new drug. The
sponsor also noticed that if the results of the local hospital were eliminated,
the sample size of the remaining sites would be adequate. He therefore decided
to terminate the study at the hospital prematurely and cut off the supply of
the drug.
Ethical Issues in
Public Health Research
·
Ethical approval
·
Individual vs. Community rights
·
Benefits vs. Risks
·
Informed consent
·
Privacy and confidentiality
·
Conflict of interest
·
Study interpretation and communication: controversial findings
Case Scenario - 1
·
A community randomized study was needed to establish whether adding
multivitamin tablets to food served in public restaurants would help reduce
cardiovascular risk. Permission was obtained from the mayor of the city since
it was not possible to get consent from each individual participant.
Case Scenario - 2
·
A new vaccine against flu was found effective overseas. The Ministry of
Health wanted to test its efficacy by a randomized study. Because of a negative
media campaign, there were no volunteers for the study. The Ministry decided to
force all hospital employees above 50 years to enter the study in the next
winter season.

Case Scenario - 1
·
A professor of cardiology conducted a well-designed post marketing
survey of a drug that had been marketed recently in Saudi Arabia but had been
marketed for over 10 years in the US and EU. Preliminary results were against
what many researchers had published and seemed even illogical to him. He told
the team of researchers to keep this information secret until the study was
completed. Analysis of the complete data confirmed the preliminary analysis.
The professor decided not to submit the results for publication for fear of his
reputation and also not to disturb other cardiologists in the country who were
satisfied with the drug.

Case Scenario - 1
·
A very experienced professor of surgery wanted to undertake research
comparing two surgical approaches that he has been using alternately over the
past 15 years. He reviewed the Nuremberg and Helsinki declarations as well as
the ICH-GCP guidelines and the Saudi regulations on research. He made sure he
fulfilled all stipulations of these documents in his research and saw no reason
to seek the approval of the local IRB that in his view consisted of young
inexperienced members most of whom had been his students. (SCHS)
Case Scenario - 2
·
A physician was given a fat grant to study a new drug. The sponsor
provided a well written and detailed protocol. Implementation of the protocol
was difficult in the local circumstances: the informed consent information was
too much and the subjects could not adhere to the visit dates fixed in the
protocol. The physician made alterations in the protocol that he thought were
simple and did not affect study validity or patient safety and saw no reason to
inform IRB/REC. The sponsor sent monitors who discovered the discrepancy. The
physician ignored their observations and continued the study without documenting
the changes he had made. (SCHS)
Case Scenario - 3
·
A physician in a local hospital agreed to be an investigator of a
multi-center international trial sponsored by the pharmaceutical company. He
regularly completed and sent CRFs to the sponsor overseas. On one occasion the
sponsor questioned the data submitted and insisted that the original patient’s
chart be shipped to him for inspection and verification. (SCHS)

Case Scenario - 1
·
The IRB of a major hospital sat to consider a proposal sponsored by a
multi-national pharmaceutical firm and all 5 members declared their interests.
The Chairman has been engaged as a temporary consultant for the firm over the
past 5 years mainly to give lectures on drug development processes to potential
researchers. The son in law of the deputy chairman had shares worth SAR1000 in
the firm acquired during course training course on stock investment. One member
was the brother in law of the principal investigator. The principal
investigator a member for 6 years had not attended the meeting. Only one member
had no interests to declare. The committee proceeded to consider the proposal
because everybody’s interests were now known. (PEER Handbook SCHS 2014)
Case Scenario - 2
·
The hospital received a big grant from a pharmaceutical company to do a
post marketing survey on a new analgesic. After trial initiation it was
discovered that the physicians in the hospital rarely prescribed the drug. The
principal investigator called a meeting of all physicians in the outpatient
clinic and asked them to start prescribing the drug so that the hospital would
not lose the grant. He explained that the drug had already been found to be
effective and was safe. (PEER Handbook SCHS 2014)
